Beschreibung
Zusammenfassung:	The double bag vacuum infusion process of the present invention provides a low cost, method for producing complex composite assemblies without an autoclave. It also enables the production of highly innovative structures. The quality of the composites produced using such an infusion process are comparable to composites made using prepregs, hand layup or fiber placement, and autoclave curing. Boeing se consacre activement à la production de cellules composites légères destinées à la fois à des applications militaires et commerciales. Un procédé de diffusion sous vide à double enveloppe de la présente invention produit une méthode de production à faible coût d'ensembles composites complexes sans autoclave. Il permet également la production de structures très innovatrices. La qualité des composites produits utilisant ce procédé de diffusion est comparable à celle des composites utilisant des préimprégnés, le laminage à la main ou le placement de fibres, et l'autoclavage.
